Today I am looking at an example of the divide and conquer method. The code is as follows:

def get_max(max_list):
    return max(max_list)


def solve(init_list):
    n = len(init_list)
    if n <= 2:
        return get_max(init_list)

    temp_list = (init_list[i:i+2] for i in range(0, n, 2))

    # print 'temp_list: ' + str(temp_list)
    print temp_list

    max_list = list(map(get_max, temp_list))

    return solve(max_list)

There are two questions:

1.temp_list生成的是tuple類型嗎？我打印出來的結(jié)果是<generator object <genexpr> at 0x00000000023570D8>, 為什么是這樣?
2. list(map(get_max, temp_list))是把map類型轉(zhuǎn)成了list, 但是這里為什么要用map呢?




if __name__ == "__main__":
    test_list = [12, 2, 23, 45, 67, 3, 2, 4, 45, 63, 24, 23]
    
    print solve(test_list)
